To all whom it may concern:

-Beit known that I, Tnnononii F. CLARK, a l citizen of the United States, residing at Seati tle, in the county of King 'and State of Wash- Improvements in Door-Chutes, of which the cllowing is a specification, reference being had therein tov the accompanying drawings, in which` l zo Figure 1 is a viront elevation of devices emodying my invention. Fig; 2 is a vertical cross-section ci the saine, and F1g.3 1s a frag;

mentary horizontal section in which the de-` vice is shown distended.

-in buildings and known as coal-chutes, though they may be utilized in various services.

zo' The invention'v consistsin the novel construction and combination of parts, as will be hereinafter described, and pointed out in the' .appended claims.

ln the drawings thereference-numeral 5 "indicates a casing adapted to be -biiilt or inserted within an opening of the lWall of a building and is formed with a ramehaving sides 6, .a to 7, and a bottom 8, of which the latter isinc ined downwardly toward the in- 3.5 adjacent surface ofthe Wallto prevent inj 7 thereto through; carelessness ie Supplying coal or the vlike vto the chut'enyj v. 'A tiltable member or. chute is hinged "to the A casing and is formed with an outer plate 11 spcndingdiniensions of the ramefopening, excepting the. f1 the lower side corners are removed to' permitl the thus-formed tapering portion entering this opening for a short dise 45' tance when the device is to be utilized as ya chute. vSecured to the inner 'side 'of' said .plate and at a distance apart slightly lessl .than the Width of the frame-opening are plates 12, forming the sides ofthe chute, and are desirably of sector shape, as shown, and

ave the apexes of the angles truncated to provide edges 13, adapted to rest upon the frame-bottoni 8, as indicated by full lines in Fig, 2, when the device is in itsclosed posi 55 tran; t

f Bigidly secured tcand extending inwardly i connected Thev object of this invention isthe. provenient in that class of devices employed side, as represented in Fig. 2. .About the in Ichutefbottoin` to 'enter .the

`bringing the chute .into theA position repreof greater length and depth than the corre? stiileningbars 14, which terminate in later#y ally-protruding bendsli" and are vtherefrom' engage with the bar l5 when the'chute is in,

,its closed position for the purposeof securing the latter against being opened fromthe ex 65,y terior of the building. Connected by straps 19 or their equivalent to the .plate l1 and adjacent to its lower edge is al rod 19', having protruding ends 19, which are slidably secured 1n journal attachments 20 of the cas-` 7c 111g. r Y 4 The operation' of the invention is as follows:

When the chuteis to be used o'rthe delivery of, say, coal or Wood, into the basement of a building, the latch-barfl7 is iirst raised up to v7`5 allowing the release the bar 15 therefrom, chute `to be tilted outwardly, until 2 it is stopped-by the bends 14 contacting with the inner flange 9 of" the casingpand the chute in thus tilting' bythe conjoint actionolfv its 8o bearing ,edges y13 against"theA juxtaposed outer corner of the 'freine andlthat of the sliding ulcruin or rod 19, being restrained in its travel, is to` a small extent raised "to pcrplate 1l or 85 init the then underedge .of .the

irameopening, sented in Fig. 3 vand bybroken lines in Fig. 2. The latch-bar meanwhile bar15 into cured vin suchclosed state by tlie',aforesaidj latchbar, and the plate'llwill actin the eato completely close the 95 pacity of adoor rame-opening. The advantages of the'invention are due ,to its neat'and attractive appearance when closed, its convenience as a coal-chute, and

in which capacity it safeguards the surroundroc ingHportions ofthe building-wall from injury. Vaving described my invention, Ywhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination with the casing-frame, 1o 5 of a chute having a sliding hinge connection therewithwhereby the bottomrof the chiite will be caused to entirely cover the openin of said frame when closed and be protruded into said opening down for use. l i i 2,. The combination with the casing-frame,

by a .transverse bai' 15. Swung '6.3 vented certain new and useful from an attachment 16 ci the frame-top 7 is is elevated by the the position indicated by,17 ingo', Fig. -2. The chute 4is .returned to its former `position by tilting it inwardly and: will be se-f when the chute is tilted a y fr..

of a chute having a sliding hinge connection therewith whereby the bottom of the chute Will be cause 'to entirely eoverthe opening of said trahie When closed and be protrnded into said opening when the chute is tilted down for use, and means to automatically lock said chute in its closed position.

3. Thecombination vwith the casing-frame, of a chute having a sliding hinge connection therewith whereby the bottom of the chute Will be caused to entirely cover the opening of said frame when closed and be protrnded into said opening when the chute is tilted down for use, means to automatically lock said chute in., its closed position, and means to limit the' extent of the outward tilting ot the chute.

4. The combination with a lcasing-trame having an'inclined bottom, and the journal attachments secured to the frame, of the chute having sides adapted to enter the opening of said frame and a bottom of greater width and length Ythan the corresponding dimensions of said. opening, said chnte-bottom being formed with a taper at one end, a horizontally-disposed rod secured to said chutebottorn and. projecting into the said attachments, bars secured to said chute sides, a bar connecting the said bars, and a latch-bar suspended from the. top of the said frame and adapted to engage with said second-named bar.

5. The combination with a casing-haine having an inclined bottom, and the journal attachments secured to the frame, of the chute having sides adapted to enter the opening of said frame and n bottom oi: greater Width and length than the corresponding diH mensions of said opening, said chute-bottom being formed with a taper at one end, a. horizontally-disposed rod secured to said chute bottom and projecting into the said attachment, diagonally-disposed bars secured to said chute sides, a bar connecting the said bars, anda latch-bar suspended Yfrom the top ol the said frame and adapted to engage with said second-named ba 6. The cmnbination with a casing-trame having an inclined bottom, and the journal attachments secured to the frame, ot the chute having sides adapted to enter the openene',

l i l l l r ing of said trame and a bottom of greater width and length than .the corresponding dimensions of said opening, said chute-bottom being ilorrned with a taper at one end, a horizontally-disposed rod secured to said chutebottom and projecting into the Said attachments, diagonally-disposed bars secured to said chute side and terminating in bends, a bar connecting the said bars, and a latchebar suspend ed from the top oi" the said trame ano'. adapted to engage with said second-named bar.

7. The combination with a casing-traine having anjllncllined bottom, and the journal attaclnnents ."seenrel to the frame, ot the chute having truncated sides adapted to enter the opening of said trame and bottoni ot' greater Width and length than the corresponding dimensions oi said opening, said chute-bottom being formed with a taper at one end, a horizontzidiy-:ilisposed rod secured to said chute-bottom and projecting into the said attachments, diagonally-di sed bars secured to saidv chute sides and terminating in bends, a bar connecting the said bars, and a latch-bar suspended from the top ol the said frame and adapted to engage with said Second-named bar. i

The combination with a casing-trame having an inclined betteln. and flanged inner and outer edges, and the journal attachments secured to the traine, of the chute having truncated sides adapted to enter the opening of said trame and a bottom ot greater `width and length than the corresponding dimensions of said opening, said chiite-bottom being formed with a taper at one end, a horizontally-disposcd rod secured to said chutek bottoml and projecting into the said attachments, diegonally-disposed bars secured to said chute sides and terminating in bends, a bar connecting the said bars, and a latch-bar suspended from the top ot the said traine and adapted to engage with said second-named har.
